Habitually cracking your knuckles for years causes trigger finger in the hands.

the verdict
CONTESTED PARTIAL
Recorded sources
1 source for · 3 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that Habitually cracking your knuckles for years causes trigger finger in the hands?

Partly. No retrieved source directly addresses whether habitual knuckle cracking causes trigger finger. One clinic page lists repetitive hand motion as a common trigger finger cause, while a hand-function study of knuckle crackers found swelling and weaker grip but no arthritis, and a reference work says trigger finger is generally idiopathic with little evidence for repetitive-use causation.
